Kwanluck's place was great! Nice, clean, well-equipped, accurate, and perfect for a month stay. I definitely recommend it. The only two things I'd note for future guests are that:
1. I was pretty worried about checking in because I didn't receive any response from the host for over a day before my arrival. But there was an envelope with everything I needed waiting for me at reception/security, and Kwanluck was otherwise very responsive. I never met her in person.
2. the building is down 2 alleys with no sidewalks coming from the metro. There is a coffee shop and street food stand right outside, but otherwise you have to take a taxi to get anywhere unless you want to walk for 10 minutes on the tiny shoulder very close to cars. The building has a free tuktuk to the metro in mornings/afternoons and there are mototaxis next to the station to get back.
